Sharing zipped .3MF containing Cura 5.0.0 profile I used to print the Core in 14h 40mins. Am no 3D printing expert, have seen folks on this forum get great prints much faster. My relatively stock Ender 3 Max, 0.6mm nozzle, 0.32mm layer height. Been couple of weeks now, but for infill, think I used doc recommendations +10%.
For smaller non Core parts I printed with faster profile. Used Cura test cubes, retraction/temp towers, CNC Kitchen, Chep, Maker Muse, Thomas Sanladerer, Teaching Tech’s https://teachingtechyt.github.io and other helpful resources.
